Publication number: 20120285218Abstract: A system and method of validating checkweigher performance (weighing accuracy). The invention involves removing an object to be weighed from a conveyor prior to the object reaching a checkweigher to be validated, weighing the object on a static scale, reintroducing the object to the conveyor upstream of the checkweigher, weighing the object with the checkweigher, and comparing the two weight readings of the object to determine if the checkweigher is accurately weighing objects. Validation objects may be automatically removed from the conveyor by a transfer mechanism.Type: ApplicationFiled: May 9, 2011Publication date: November 15, 2012Applicant: METTLER-TOLEDO, INC.Inventor: Eric Inglin

Publication number: 20110290567Abstract: A system and method for assisting a party (e.g., a freight carrier) in determining whether dimensional weight or actual weight should be used for shipping particular freight. A weighing device may be associated with a forklift, and may also include a DIM comparator in association with the forklift. The DIM comparator may have an input and a display of information, and may also include a CPU unit for storing and processing data. The DIM comparator may allow an operator to input various data through selectable menus and tables. The DIM comparator then determines a theoretical dimensional weight of the freight and compares it to the actual weight as measured by the weighing device associated with the forklift. This comparison is then displayed to the operator and a prompt is provided if a dimensional weight should be determined.Type: ApplicationFiled: June 1, 2010Publication date: December 1, 2011Applicant: Mettler-Toledo, Inc.Inventors: Dana Waggoner, Jon Hayes, Barry McDonald

Patent number: 8035042Abstract: A coupling device designed to securely connect adjacent weigh platform modules of a vehicle scale. Such a device may include corresponding coupling elements, each adapted for attachment to a respective one of a pair of adjacent weigh platform modules. The coupling elements are designed for mating contact and include fastener assembly receiving cavity sections that, when the coupling elements are properly mated, form a fastener assembly receiving cavity in an exposed top surface of the coupling device. A fastener assembly is located in the fastener assembly receiving cavity and is operative to secure the mated arrangement of the coupling elements, thereby rigidly connecting the associated weigh platform modules. The accessible location of the fastener assembly facilitates both installation and subsequent service/repair procedures.Type: GrantFiled: March 25, 2009Date of Patent: October 11, 2011Assignee: Mettler-Toledo, Inc.Inventors: Jeff Budic, Aaron Skidmore

Publication number: 20110162456Abstract: An ultrasonic dimensioning system and method by which objects can be quickly and accurately measured (dimensioned). The system includes at least a stable object support surface, a number of ultrasonic receivers, and an ultrasonic transmitter. The ultrasonic transmitter is preferably part of a pointer device that is properly positioned relative to an object to be measured, the proper position(s) depending on the shape of the object. Subsequent transmission of ultrasonic pulses (waves) from the pointer device are received by the ultrasonic receivers. The time intervals between transmission and reception of the ultrasonic pulses (waves) are used to determine the distance of the pointer from the receivers, which distances are subsequently used to calculate the dimensions/volume of the object.Type: ApplicationFiled: March 16, 2011Publication date: July 7, 2011Applicant: METTLER-TOLEDO, INC.Inventors: Wenquan Li, Philip M.

Publication number: 20110147097Abstract: An intermittent motion checkweigher for weighing products of interest. The checkweigher includes a product transport wheel having a plurality of product retention pockets, each of which retainins one or more products of interest throughout the weighing operation. Products are loaded into a product retention pocket by an in-feed conveyor or similar device, after which the product transport wheel is indexed to advance the products in the product retention pocket toward one or more weighing devices where the products will be weighed while still located in the product retention pocket. After weighing, the products are advanced to a discharge conveyor or similar device by further indexing of the product transport wheel.Type: ApplicationFiled: December 17, 2009Publication date: June 23, 2011Applicant: METTLER-TOLEDO, INC.Inventors: David Troisi, Josh White

Patent number: 7875813Abstract: Food service workers prepare a number of items throughout the day at a food counter, so the workers may need to track process steps for entirely different processes that are running concurrently. For example, the worker may need to remove a pizza from an oven one moment, and remove breadstick dough from a refrigerator one minute later. A programmable weighing scale guides users through process steps of a process, and tracks completion time of process steps for multiple processes, and alerts a food service worker when a next step in one of multiple, concurrently running processes needs to be completed. Because data stored for each process can be selected throughout, for example, an entire working day, the controller of the weighing scale can track timing requirements for each step of each process. The weighing apparatus is independent of other apparatuses used in completing the process steps (e.g., refrigerators, ovens, mixers, etc.Type: GrantFiled: April 4, 2007Date of Patent: January 25, 2011Assignee: Mettler-Toledo, Inc.Inventors: Daniel J.

Publication number: 20100314177Abstract: A checkweigher for the in-motion weighing of objects being transported along a conveyor line. A checkweigher of the present invention employs a plurality of scales each having its own set of weighing conveyor elements. For example, a first scale may be associated with a set of lighter weight chains to convey and weigh smaller objects, while a second scale may be associated with a set of heavier weight chains to convey and weigh larger objects. This design essentially allows the incorporation of a lightweight and heavyweight checkweigher within one common checkweigher frame. The problem of noise caused by one set of conveyor elements associated with one scale affecting the accuracy of the other scale(s) is eliminated by locating the conveying surfaces of the conveyor elements associated with the individual scales in different planes. Thus, objects transported by one weighing conveyor exert no load on the conveyor elements of the other weighing conveyor(s).Type: ApplicationFiled: June 16, 2009Publication date: December 16, 2010Applicant: Mettler-Toledo, Inc.Inventors: David Troisi, Daron King

Patent number: 7812267Abstract: A weighing apparatus having a weighing system, a drive system, and a vertical force minimizing system. The weighing system may include a load receiving surface and a plurality of load cells. The drive system produces rotation of the load receiving surface about its vertical axis. The vertical force minimizing system minimizes the amount of vertical force that is applied to the load cells through the drive system, while simultaneously transmitting forces in the transverse direction to provide for rotational movement of the load receiving surface.Type: GrantFiled: July 21, 2008Date of Patent: October 12, 2010Assignee: Mettler-Toledo, Inc.Inventors: Craig M. Draper, Thomas S. Rice

Publication number: 20100251833Abstract: A device and method for effectuating the temperature compensation testing of digital load cells. The device uses conductive heat transfer to establish and maintain the temperature of the load cell(s) during testing. The device may include a vessel into which one or more load cells to be tested are placed. Temperature control of the load cells may be accomplished by circulating a temperature controlled fluid through the vessel. The vessel containing the one or more load cells may then be placed in a load application device that applies a load(s) to the one or more load cells during testing. Readings from the one or more load cells are used to establish a temperature compensation factor for each load cell tested. In other embodiments, temperature control of the load cells may be accomplished by placing the load cells in contact with a solid heat transfer element(s).Type: ApplicationFiled: April 3, 2009Publication date: October 7, 2010Applicant: Mettler-Toledo, Inc.Inventors: Daniel Reber, Urs Loher, Aaron Skidmore
